Abstract

A method and apparatus for use with an oxidizer assembly of a fuel cell system in which the oxidizer assembly has an oxidizing unit for oxidizing anode exhaust gas containing electrolyte particulates and is adapted or conditioned so as to enable the electrolyte particulates to be removable from the assembly and to be removed from the assembly, and wherein the conditioning and removing occur with the oxidizing unit retained in the oxidizer assembly. The fuel cell system is also adapted so that such conditioning and removing occur with the oxidizing assembly retained in the fuel cell system.
